Chapter 3, Problem 3.18E

Interpretation Introduction

Interpretation:

The value of $\text{c}\left(\text{t}\right)$ needs to be calculated which is the exit concentration and it needs to be plotted as a function of time.

Concept introduction:

The Laplace transform of a time-domain function $\text{f}\left(\text{t}\right)$ is represented by $\text{L}\left[\text{f}\left(\text{t}\right)\right]$. It is defined as follows:

$\text{L}\left[\text{f}\left(\text{t}\right)\right]\text{=f}\left(\text{s}\right)\text{=}{\int }_0^{\infty }\text{f}\left(\text{t}\right){\text{e}}^{\text{-st}}\text{dt}$.

An integral transform equation is named as Laplace transforms equation after the inventor Pierre-Simon Laplace. This transform equationhas many applications in science and engineering field. This transformation is used to transfer a real variable $\left(t\right)$ into function of complex variable $\left(s\right)$.
